 complete tables as Richardson has done for the Arctic regions?  and
 if we could, would it be worthwhile unless we could add as complete series
 of [thermometrical?] observations, which we have as yet no means of obtain-
 ing.  It might be interesting to add a comparative statement of the

 [illegible] production.
